Granular B Type I does not require crushing. Granular B Type II is crushed and hence may only be obtained from quarried rock, blast furnace slag, or nickel slag. Maximum size of Granular B Type II may be 150 106, or 75 mm. Granular B Type III is similar to Type I except it does not allow the use of uniform or poorly graded fine sands.
